Try this:

PHP код:

CMD:playmusic(playerid, params[]) 
{ 
        if(IsPlayerInRangeOfPoint(playerid, 10.0, 260.4326,-1809.4899,6.9791))  
        {  
            if(isnull(params)) return SendClientMessage(playerid,0xf8f8f8fff, "Syntax: {FFFFFF}/playmusic <Link>"); 
            foreach(Player, i)   
            { 
                PlayAudioStreamForPlayer(i, params); 
            } 
        } 
        return 1; 
} 


EDIT: you're doing right, just include params as it is without " "
